How does space-time work? Einstein, however, introduced the concept of time as the fourth dimension, which meant that space and time were inextricably linked. His general theory of relativity (opens in new tab) suggests that space-time expands and contracts depending on...
Is spacetime a real fabric? First of all, space-time is not a fabric. Space and time are not tangible ‘things’ in the same way that water and air are. It is incorrect to think of them as a ‘medium’ at all....
What is the theory of relativity by Einstein? Relativity is a theorem formulated by Albert Einstein, which states that space and time are relative, and all motion must be relative to a frame of reference. It is a notion that states’...
Where is Einstein’s brain now? Finally, in 1998, Harvey–who died in 2007–gave the jar to the University Medical Center of Princeton, where it remains today. The first anatomical study of Einstein’s brain was published in 1999, by a team led by...
What is Einstein’s general theory of relativity equation? One of the most famous and well-known equations in all of human history, E = mc^2, translates to “energy is equal to mass times the speed of light squared.” In other words, wrote...
Why is Einstein’s theory of relativity important? In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as...
When did Einstein come up with the theory of special relativity? It was pondering these developments that led Einstein to discover the special theory of relativity in 1905. The discovery was not momentary. The theory was the outcome of, in Einstein’s...
How did Einstein discover that E MC2? Would light waves have time to bounce off their face, hit the mirror, and bounce back to their retina which was also moving at the speed of light? And what if an observer was...
What is Albert Einstein’s theory about gravity? He theorized that a mass can prod space plenty. It can warp it, bend it, push it, or pull it. Gravity was just a natural outcome of a mass’s existence in space (Einstein had,...
Does gravity make time go slower? This form of time dilation is also real, and it’s because in Einstein’s theory of general relativity, gravity can bend spacetime, and therefore time itself. The closer the clock is to the source of gravitation,...
